Begitknown that- I, Rossa jNewsom),

aciti'zen of the United States, residing 'at Chicagq county of. Coeli, and State of vIllinois, lia-veinvented certain new and'usefu'l *improvements in.. Battery-Terminals, of

fwliich the lfollowing is a specifi-cation and which are4 illustrated in the accompanying draft-rings, forming a partthereof. .The -invention relates --to terminals for,

storage or secondary-batteries having for tive branches of an electric circuit with` f1.5,

its object the Vprovision of in ans for insuring-the connection of the positive and negathe positive and negative poles-,respect-ively,

. of the battery'.

In 'certain situations, as in .the electric systems of automobiles, it is becominga .common practice to lprovider al dynamo driven by the engine of 'the Vehicle and which not only provides( :urrentfiforv the -1amps fand for' the engine iignitionv 'hut y charges a'st'orage batterywvhich supplies the current for the lamps' V'when the engine .is

i; formed that. it is impossible to connect atl not running. In such-systems it. is, of

course, essentialtliat lthe positive and nega- :tive leads from the dynamo be Vconnected,V respectively, with thepositive and negativev poles of the battery. Ordinarily the. op-

erators-havingthe care of such vehicles are' Withoutelectrical training, and in such hands suchfsystems' become unreliable because of fliedangerpof the connections being madeV improperly.

-The'invention'- consists in terminals so .least one of the branches of the circuit with 'the Wrong pole of theblfittery.

" `In the accompanying drawings Figure 1 sented at 10; one of its terminals, rvhic -indicated'as the positive terminal, is shown at 11, and theotlier, indicated as the nega# is a `detail of the upper portion of astorage battery showing itsterminal's; Fig. 2 is sectional-view on the-line 2-'-2 of Fig. 1;A Fig. 3 is a sectional view .ontlie line 3*?,

of` Fig.- 1; Fig. lis a detail of the terminal lof'one, Whi'chniav be designated the negative, branch of the circuit; Fig. 5 is a detail of the corresponding batte-rv terminal; Fig. 6 is a detail of theterininal ot the other branch of the circuit; andFig. -7 is a de j; -tail of the other terminal or" the battery.

A portion of a storage batteryY is rei i tiveA terminal, shown' at- '12. The upper ends13, 14, of theseterninals"are-Hattened, and thr'oughthe flattened portion of by. preventiingrr 4the 'stud `from turning. -A nut, as 19, 20, is 'applied to Vthe rearward projecting end of each stud to securely-bind it in place, drawing the boss into.l the recess provided. for it.V The forivardlend 21, 22,v receives the eve of the line. terminals 23, 24,.

andnuts 25, 26, applied to the forward projecting ends of the studs, hind-these ter-v minals in place.

The recess 0f the 'positive terminal is in vviisrLAxEf the form ofa channel extendingentirely v across its front face, thus providing pockets 2", 28, ateither side of the boss 17. The line terminal'23 coperating'ivith the positive terminal 11, is provided with a pairof laterall)r projectinfzlugs 29, 30Which enter these pockets. The recess formed inA the terminal 12 for receiving the boss 18 is of the saine shape as the boss and' of such size as to provide a snug litl therefor, so that` a VVflattened face of the terminal extension 14 is .provided for a. correspondingface of the vline terminal 34. The studs 21, l22, are of such length that their forwardV ends project but a short distance bevond the line ter- .minals. and hence should an' attempt be made to apply thev terminal 23 to the batter;7 terminal 12 its outer face would be even -with or project bevond the end of the stud. thus rendering it impossible to apph7 the securing' nut 2G. vThe. operator would post and 'irojecting bevond the channel, a line terminal having `an eye for receiving p i. ln terminals for storage batteries. inv kombination. a post.' havin;r a transverse ,ciiannci. a 'thri'a'ded stud set through the the stud, and lugs for entering the chan# nel, and a nut engaging the threaded end ofthe stud. l

2. In terminals for storage batte-ries, in

5 combination, a'pairof posts, threaded studs differing in length set through the posts, a pair ot' line terminals each having an eye for receiving one of the studs, such terminals being of unequal thickness, andnuts engaging the ends of the'studs.

3. In terminals for storage batteries, in combination, a pair of flattened posts each having an aperture in one of its a'ces,` the aperture in onel only of the posts beingn L'mgsn the form of a channel extending aoross the,15 post face, threaded studs set through each y. z post and passing through and beyond `-'the aperture thereof, a pair Q'fline terminals each having an eye for engagingl one of the studs, one ofsuch terminals having a flat face forbearingagainst the post .and-'the otherof such terminals having lateral' .lugs

for enteringv the post channel, a'ndnuts ene.
